SPECIFICATION forming part of VLetters. Patent No. 651,702, dated June 12, 1900. Application filed October 23, 1899. Serial No.'734,428. (No model.)

To all whom t may concern-.-

Be it known that I, GEORGE O. DRAPEE, of IIopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Spinning Apparatus, of which the following description, in connection with the accompanying drawings, is a speciiication, like letters on the drawings representing like parts.

This invention has for its object the production of simple, cheap, and eiiicient spinning apparatus belonging in general to the dead-spindle type, although in many particulars my invention differs therefrom, as will appear more fully hereinafter.

In the apparatus forming the subject-matter of this invention the bobbin, or yarncarrier, as I shall term it, is rotatable directly upon the dead-spindle and is frictionally connected with a whirl, the latter being centered and carried by the yarn-carrier when I the latter is in running position.

Figure l is a vertical sectional View of spinning apparatus embodying myinvention, and Fig. 2 is a detail of a modification to be described.

Referring to Fig. l, I have shown a holder B for the dead-spindle A, said holder having a threaded shank B to enterahole in the ordinary rail and receive a retaining-nut BX, whereby the holder and spindle are maintained in position on the rail. The hollow shank is shown as threaded interiorly at its lower end to receive an endv support bx, though obviously the shank could be formed with an integral bottom. The lower end of the deadspindle is shown as extended into the holder, and a suitable packing P may be interposed between the spindle and holder, if desired, to obviate any undesirable vibration which might otherwise be set up in the spindle when rotating the yarn-carrier at high speeds, the friction of the packing preventing rot-ation of the spindle. Instead of a packing a bolster might be employedfor the same purpose, as shown at II, Fig. 2, fitting loosely into the holder B but in either case the spindle is held from rotation in the holder. In using a bolster any one of many well-known devices could be used to prevent rotation of the bolster, such as a pin on the holder engaging a notch in the bolster, the spindle `fitting tightly in the bolster.

A preferably metallic whirl D, shown as having a large downwardly-tapering bore and the usual hand-receiving groove d, has secured to ita wooden or other suitable fibrous collar d', said collar surrounding the deadspindle A; but the bore d2 of the collar is larger than the diameter of the spindle in order that the collar shall be out of contact therewith when in operation. As shown in Fig. l, this collar rests upon an end bearing b2, formed, conveniently, by an upturned portion of the holder B. A suitable guard g is mounted on the holder to projectoverashoulder d5 on the Whirl and prevent withdrawal thereof with the yarn-carrier.

The yarn-carrier O is made, preferably, of wood, with an exteriorly-tapered base c to enter and frictionally engage the tapered bore of the whirl, the yarn-carrier having at its lower end a bearing portion c to engage the spindle with a running fit, While the counter-v bore c2 has a Wooden or fibrous bushing c3 in serted therein at its upper end to engage the spindle also with a running fit. As herein shown, the upperbearin g c3 engagesa reduced portion ct of 'the spindle. When the yarn carrier is placed on the spindle, it is pushed down 'into the Whirl and acts to center the latter on the spindle, so that the collar d is held from contact with the spindle, the whirl being carried by the yarn-carrier. When the yarn-carrier is removed, the whirl runs on the spindle by means of the collar CZ. The bearings c and c3 and also the collar d are soaked or thoroughly impregnated with an antifriction compound, and the wear is thus reduced to a minimum.

The use of oil is entirely obviated by the construction shown, and the construction is at once simple and highly efficient, while the cost of production is very greatly reduced.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. A dead-spindle, a yarn-carrier having contained non-metallic bearings, to run directly upon the spindle, and a Whirl loosely surrounding the spindle and adapted to be engaged and oentered by the yarn-carrier', and maintained thereby out of 'Contact Vwith l the spindle. i
